Abstract

PROBLEM TO BE SOLVED: To detect a rotating position of a lever. SOLUTION: A first connector 20 is structured by assembling a cover 50 to a housing 21, and a sliding member 40 having a cam groove 41 and a lever 70 are respectively attached to the housing 21 and the cover 50. As the sliding member 40 slid from an initial position to a fitting position by interlocking with rotations of the lever 70 from an initial position to the fitting position, cam action is exerted by engagement between a cam groove 41 and a cam pin 12 of the second connector to fit both connectors 10, 20 with each other. On a rear wall 52 of the cover 50, an installing recessed portion 58 to which a detecting member 80 is attached is provided. In a state that the detecting member 80 is arranged at a standby position, till the lever 70 achieves the fitting position, an arm portion 71 is always arranged above the detecting member 80, thereby regulating movement of the detecting member 80. A notch portion 78 matching the detecting member 80 when achieving the fitting position is formed on the arm portion 71 of the lever 70, thereby accepting the movement to a detecting position of the detecting member 80.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a lever-type connector.

[0002]

2. Description of the Related Art Conventionally, a lever type connector is disclosed in Japanese Utility Model Laid-Open No. 5-36774. This is because the first connector rotatably supports the lever, the second connector is provided with a cam pin that engages with the cam groove of the lever, and both connectors are shallowly fitted to engage the cam pin with the cam groove. When the lever is rotated in this state, both connectors are pulled together by the cam action by the engagement of the cam groove and the cam pin to reach the fitted state.

[0003]

In the case where the connectors are fitted to each other by using the lever as described above, a certain amount of operating force is required to rotate the lever. Without rotating completely to the mating position,
The rotation operation ends halfway in the half-fitted state,
I'm concerned. In this case, if the turning position of the lever is far away from the regular fitting position, it can be easily discerned visually, but if the lever remains at the position immediately before the regular fitting position, It is difficult to visually determine whether or not it has been rotated to the fitting position. The present invention has been completed in view of the above circumstances, and an object thereof is to detect the turning position of a lever.

[0004]

As a means for achieving the above object, the invention of claim 1 is one in which a lever is rotatably mounted on a first connector, and the lever is fitted from an initial position. In a case where a cam action is exerted between the lever and the second connector to rotate the lever to the mating position so that the two connectors are fitted to each other, the first connector has a rotation direction of the lever. A detection member movable between a standby position and a detection position along a substantially orthogonal direction is mounted, and the detection member arranged at the standby position is until the lever reaches the fitting position. Movement to the detection position is restricted by interfering with the lever, and when the lever reaches the fitting position, it does not interfere with the lever retracted from the front in the moving direction, and the movement to the detection position is allowed. In the place where With a butterfly.

According to a second aspect of the present invention, in the first aspect, the detection member is provided inside the mounting portion provided by being retracted inward from an outer surface of the first connector which is substantially orthogonal to a rotation direction of the lever. It is characterized in that the outer surface of the mounted detection member is arranged at a position flush with the outer surface of the first connector or at a position retracted inward.

According to a third aspect of the present invention, in the first or second aspect, when the detection member reaches the detection position, the front surface in the moving direction of the detection member is flush with the outer surface of the lever. It is characterized in that it is arranged at a position that makes up or is retracted backward in the moving direction.

[0007]

<Advantages and effects of the invention><Invention of claim 1> When the lever is rotated to the fitting position, the lever is retracted from the front in the moving direction of the detection member, which is the standby position, and therefore the detection member is moved. When doing so, the detection member does not interfere with the lever and can be moved to the detection position. Therefore, it is detected that both connectors are properly fitted. On the other hand, if the lever does not reach the fitting position, the lever is arranged in the front in the moving direction of the detection member, which is the standby position. Therefore, even if an attempt is made to move the detection member, it interferes with the lever and moves it to the detection position. I can't. Therefore, it is detected that the lever does not reach the fitting position and both connectors are in the half fitting state. That is, the turning position of the lever can be easily determined based on whether or not the detecting member can move to the detecting position.

<Invention of Claim 2> Since the detection member mounted in the mounting portion is housed without protruding from the outer surface of the first connector, the outer shape can be made clean. <Invention of Claim 3> Since the detection member is housed without protruding from the outer surface of the lever when the detection member is moved to the detection position, the outer shape of the lever-type connector can be kept simple.

In the following, the mating surface side of both connectors 10 and 20 will be referred to as the front, the left and right descriptions will be based on FIGS. 1 to 5, and the upper and lower descriptions will be FIGS. 1 and 6 to 11.
Will be described as a reference.

The second connector 10 is, as shown in FIG.
The first connector 20 has a square tubular hood portion 11 that is openable to the front and can fit therein, and a plurality of terminals (not shown) are provided in the hood portion 11 so as to project. Two substantially cylindrical cam pins 12 are erected on the upper and lower outer surfaces of the horizontally long portion of the hood portion 11.

As shown in FIGS. 1 and 2, the first connector 20 includes a housing 21 for accommodating a plurality of terminal fittings (not shown) which can be conductively connected to the terminals of the second connector 10.
And a cover 50 that covers the housing 21 from the rear side. The housing 21 is composed of a terminal accommodating portion 24 having a plurality of cavities 23 into which the respective terminal fittings can be inserted from the rear, and an outer cylindrical portion 25 surrounding the cavity, and a space between the terminal accommodating portion 24 and the outer cylindrical portion 25. The hood portion 11 of the second connector 10 can be fitted to the front. A lever accommodating groove 26, into which the lever 70 can be inserted from the rear, is formed on the rear surface of the outer tubular portion 25 with a predetermined width (a range allowing the rotation of the lever 70). On both side surfaces of the outer tubular portion 25, slide member accommodating grooves 27 are formed so as to be opened in the width direction, and slide members 40 interlocking with the lever 70 are laterally assembled therein. A slide member accommodating groove 27 is formed so as to communicate with the lever accommodating groove 26 inward in the radial direction.
The hood portion 11 of the second connector 10 is inserted into the inside of 7.

The slide member 40 is formed in a gate shape when viewed from the front, and two cam grooves 41 that open to the front are formed in the upper and lower horizontally long portions, and an engagement groove that opens to the rear is formed. 42 are formed respectively. Both cam grooves 4
1 is formed to be inclined leftward and rearward from the entrance 41a at the front end, and the cam pin 12 of the second connector 10 is formed here.
Are engageable with each other. In addition, a cam pin insertion hole 28 that can be aligned with both cam grooves 41 is provided at the front end portion of the outer tubular portion 25.
The openings are formed one by one. The protrusion 75 of the lever 70 is rotatably engaged with the engagement groove 42. An elastic locking piece 43 is provided on the right side of the rear end of the laterally long portion of the slide member 40 so as to be flexibly deformable in the front-rear direction. The cam groove 41 of the slide member 40 is aligned with the cam pin insertion hole 28 by being locked in the locking hole 29 formed,
Moreover, the engaging groove 42 can be held at the initial position aligned with the projection insertion hole 31 described later. From this initial position, the slide member 40 is linearly slidable rightward along the width direction (direction orthogonal to the fitting direction), is completely housed in the slide member housing groove 27, and is the cam pin. The movement of 12 to the fitting position (FIG. 5) reaching the rear end of the cam groove 41 is allowed.

As shown in FIG. 2, the cover 50 is formed into a substantially box shape having front and right side surfaces open, and a peripheral wall 51 composed of three walls surrounding the upper and lower surfaces and the left side surface of the rear portion of the housing 21. And a rear wall 52 that connects the rear ends of the peripheral wall 51.
It consists of and. At the front end portion of the peripheral wall 51, three elastic holding pieces 53 that can be engaged with the holding projections 30 formed on the rear side surface of the housing 21 are formed, whereby the cover 50 is held on the housing 21. In the cover 50, the electric wire led out from the rear surface side of the housing 21 is bent and can be drawn out through the opening portion on the right side of the cover 50. In addition, on the left side of the rear end of the cover 50, a relief portion 54 for escaping the lever 70 is formed to be recessed as described later.

At the central portions of the upper and lower outer surfaces of the laterally long portion of the peripheral wall 51, mounted portions 55 on which the lever 70 can be mounted are formed so as to be raised one step higher. Both mounted parts 55
At the center of each of the shafts, a substantially columnar shaft portion 56 for supporting the lever 70 is erected. The lever 70 is generally gate-shaped by connecting the ends of a pair of upper and lower plate-shaped arm portions 71, 72 with the operating portion 73, and is opened at substantially the center positions of both arm portions 71, 72. By fitting the provided long hole 74 into the shaft portion 56, the elongated hole 74 is supported rotatably in parallel with the width direction with respect to the cover 50. A cylindrical projection 75 is provided on the inner side surface of each of the arm portions 71, 72 at the end opposite to the operation portion 73 side so as to project from a position in the vicinity of the peripheral portion. Also, the outer cylinder portion 25
A protrusion insertion hole 31 is formed in the rear end portion to allow the protrusion 75 to enter the slide member accommodation groove 27 when the lever 70 is inserted into the lever accommodation groove 26. The elongated hole 74 described above extends substantially parallel to a line connecting the substantially central positions of the arm portions 71 and 72 and the protrusion 75.

The lever 70 covers the operating portion 73 when the operating portion 73 is brought into contact with the rear wall 52 of the cover 50 and the projection 75 is positioned diagonally left front of the elongated hole 74 (FIG. 2). The shaft portion 56 is rotatable with respect to the fitting position (FIG. 5) in which the protrusion 75 is located in the relief portion 54 and the protrusion 75 is located diagonally right forward of the elongated hole 74. However, since the elongated hole 74 is displaced relative to the shaft portion 56, the position of the rotation center of the lever 70 itself moves along the elongated hole 74 as the lever 70 rotates. A holding projection 57 is provided at a position diagonally rearward and rightward of the shaft portion 56 of the mounted portion 55, whereas the holding projections 57 are provided on the arm portions 71 and 72 when the lever 70 is at the initial position. Initial position holding hole 76 (Fig. 2)
And a fitting position holding hole 77 (FIG. 5) that is engaged with the holding projection 57 at the fitting position, thereby allowing the lever 70 to be held at both positions.

The cover 5 with the lever 70 mounted in the initial position
When 0 is attached to the housing 21, the arm portions 71, 7
Part of the peripheral edge portion of 2 is inserted into the lever accommodating groove 26, and the projection 75 is located in the slide member accommodating groove 27 through the projection insertion hole 31. 42 is engaged. By engaging the projection 75 with the engaging groove 42, the pivotal movement of the lever 70 and the sliding movement of the slide member 40 can be mutually converted. Therefore, when the lever 70 is rotated from the initial position to the fitting position, the slide member 40 interlocks to reach the fitting position from the initial position, and is exerted by the engagement between the cam groove 41 and the cam pin 12 during this period. Both connectors 10 and 20 are fitted by the cam action. In this way, the protrusion 75 of the lever 70 and the slide member 40 having the cam groove 41 constitute a cam function means for fitting the connectors 10 and 20 by the cam action.

Now, as shown in FIGS. 6 and 7, an upper portion of the rear wall 52 of the cover 50 in the substantially central portion in the width direction (see FIG. 2).
(The front side of the paper of FIG. 2) and a mounting recess 58 that opens rearward are formed by partially recessing the mounting recess 58 inward.
The detection member 80 can be mounted inside from above. The mounting recess 58 is formed so as to be recessed inward from a rear surface 52a (an outer surface orthogonal to the rotation direction of the lever 70) of the rear wall 52 excluding the mounting recess 58. The detection member 80 is
The mounting recess 58 is movable in the up-down direction (direction orthogonal to the rotating direction of the lever 70).

The detection member 80 has a flat plate-shaped main body 81 having a width slightly smaller than that of the mounting recess 58. Inside the mounting recess 58, the main body 81 has a rear surface of the mounting recess 58 and a side surface of the mounting recess 58. By being sandwiched between the pair of support walls 59 formed so as to project inward from the rear end portion, they are supported without rattling forward and backward. A pair of cantilevered holding arms 82 that are elastically deformable along the width direction by forming substantially L-shaped slits are provided on both sides of the main body 81. The tips of both holding arms 82 are formed in hook shapes projecting to the outside, and the hook portions are provided on the left and right sides of the mounting recess 58 in pairs, and the lower holding position holding groove portions 60 and the upper detection portions are provided. The detection member 80 can be held in two positions, that is, a lower standby position (FIGS. 8 and 9) and an upper detection position (FIGS. 10 and 11) by being respectively engaged with the position holding groove portions 61. It is like this. The holding groove portion 60 for the standby position and the holding groove portion 61 for the detection position are provided on the rear wall 5.
The second rear surface 52a is formed to have an opening.

At the standby position, the detection member 80 is mounted on the main body 8
The lower surface of No. 1 is arranged close to the lower surface of the mounting recess 58, whereas the upper surface 81a (front surface in the moving direction) of the main body 81 is slightly retracted below the upper surface (outer surface) of the upper mounted portion 55. The upper arm portion 7 of the lever 70 is arranged by
No interference with No. 1 (FIGS. 8 and 9). Then, until the lever 70 reaches the fitting position from the initial position, a part of the arm portion 71 (the operation portion 73 and the long hole 7) is always located above the detection member 80 (forward in the moving direction of the detection member 80).
4) is arranged. Therefore, even if the detection member 80 is moved upward from the standby position, the arm portion 7
When the detection member 80 abuts on the lower surface (the surface along the rotation direction) of 1, the upward movement operation thereof is restricted. On the other hand, the detection member 8 is provided on the right side edge of the upper arm 71 in FIG. 2 (the rear edge of the arm 71 at the fitting position in FIG. 5).
A cutout portion 78 is formed along the outer shape of 0 (front surface and left side surface of the detection member 80), and the cutout portion 78 is aligned with the detection member 80 only when the lever 70 reaches the fitting position. (Fig. 5). Therefore, when the lever 70 is in the fitting position, the arm 71 is retracted from the upper region of the detection member 80, which is the standby position. Therefore, when the detection member 80 is moved upward, the detection member 80 moves. Therefore, the movement to the upper detection position is allowed while the inside of the notch 78 is entered. Then, at the detection position, in the detection member 80, the main body 81 protrudes from the upper surface of the mounted portion 55, and
The upper surface 81a is arranged so as to be retracted below the upper surface 71a (outer surface) of the arm portion 71 by a predetermined height (rearward in the moving direction of the detection member 80) (FIGS. 10 and 11). At this time, the protruding portion of the main body portion 81 from the mounted portion 55 is arranged close to the peripheral surface (the surface orthogonal to the rotation direction) of the cutout portion 78 of the arm portion 71, and both should abut. Thus, the operation of rotating the lever 70 from the fitting position to the initial position side is restricted.

As shown in FIG. 6 and FIG. 7, a retaining projection 83 that can enter into the escape groove 62 formed on the rear surface of the mounting recess 58 is formed in the lower center of the front surface of the main body portion 81 in the width direction. It is provided. A stopper portion 63 is formed so as to project in the middle of the escape groove 62. In the standby position, the retaining protrusion 83 is located below the stopper 63 (FIG. 8), whereas in the detection position,
By locking the upper surface of the retaining projection 83 to the lower surface of the stopper portion 63, it is possible to prevent the detecting member 80 from being displaced upward (FIG. 10). Also, the retaining projection 83
The retaining projections 8 are provided on the lower surface of the and the upper surface of the stopper portion 63.
A tapered surface is formed for facilitating the operation of the vehicle 3 riding on the stopper portion 63.

An operation projection plate 84 which is elongated in the width direction is provided in the widthwise center of the upper portion of the rear surface of the main body 81, and the detection member 8 is pressed by pressing the operation projection plate 84.
You can move 0 up and down. Operation veneer 84
A pair of guide ribs 85, which are slightly lower than the operation projection plate 84, are formed on the upper surfaces of both sides of the above so as to extend upward. The upper and lower movements of the detection member 80 are guided by the inner side surfaces of both support walls 59 slidingly contacting the outer side surfaces of the operation projection plate 84 and both guide ribs 85. When the detection member 80 is mounted, the rear surface 84a of the operation projection plate 84 is aligned at substantially the same position as the rear surface 52a of the rear wall 52 of the cover 50 excluding the mounting recess 58, in other words, is substantially flush. .

The present embodiment has the structure as described above, and its operation will be described subsequently. In order to assemble the first connector 20, first, the detection member 80 is mounted in the mounting recess 58 of the cover 50 at the standby position, and then the lever 70 is mounted so as to be sandwiched with respect to the cover 50 and held at the initial position. deep. At this time, as shown in FIG.
Since the arm portion 71 is arranged above 0, the upper surface 81a of the main body portion 81 will be the lower surface (inner surface) of the arm portion 71 even if a force acts to move the detecting member 80 upward. The movement of the detection member 80 is restricted and the detection member 80 is prevented from being accidentally moved to the detection position.

On the other hand, the slide member 40 is attached to the housing 21 and held at the initial position. Next, the cover 50 equipped with the detection member 80 and the lever 70 is assembled from the rear of the housing 21 equipped with the slide member 40. With the assembly, the lever 70 is inserted into the lever accommodating groove 26, and the projection 75 is inserted into the slide member accommodating groove 2.
7 and is engaged with the engaging groove 42 of the slide member 40 (see FIG. 2).

Subsequently, the fitting operation of both connectors 10 and 20 is performed. First, with respect to the first connector 20, the second connector 10
Lightly fit the hood portion 11 of, and as shown in FIG.
Pass the cam pin 12 through the cam pin insertion hole 28 and the cam groove 41.
To enter the entrance 41a. From this state, the operation unit 73
Is operated to be displaced substantially to the left, and the lever 70 is rotated to the fitting position side. As the lever 70 rotates, the projection 75 presses the inner wall of the engagement groove 42 to the right as shown in FIGS.
Slides to the fitting position side (right side) in conjunction with 0. The cam groove 41 and the cam pin 1 accompanying the movement of the slide member 40.
A cam action is exerted by the engagement with 2, and the second connector 10 is pulled toward the first connector 20 side. In this process, the long hole 74 is relatively displaced with respect to the shaft portion 56, and the rotation center of the lever 70 itself moves along the long hole 74. It is moved linearly along the direction.

In this rotating process, the arm portion 71 is always arranged above the detection member 80 at the standby position. Therefore,
For example, even when the operator tries to move the detection member 80 by mistakenly recognizing that the lever 70 has reached the fitting position, the main body 81 hits the arm 71. As a result, the movement is restricted, so that it is detected that the connectors 10 and 20 are half-fitted.

When the lever 70 reaches the fitting position, the slide member 40 reaches the fitting position and the cam pin 12 is arranged at the rear end of the cam groove 41, as shown in FIG. As a result, both connectors 10 and 20 are fitted to the normal depth. At this time, the cutout portion 78 is arranged at a position aligned with the detection member 80, and the arm portion 71 retracts from the region above the detection member 80. The fitting work may be performed by operating the slide member 40 instead of operating the lever 70. In that case, by pushing the slide member 40 at the initial position toward the detection position and sliding it, the cam groove 41
The cam action is exhibited by the engagement of the cam pin 12 with the cam pin 12. As the slide member 40 slides, the inner wall of the engagement groove 42 presses the protrusion 75 to the right, whereby the lever 70 is interlocked with the slide member 40 and rotated from the initial position to the fitting position. .

When the lever 70 is completely rotated, the detecting member 8
Work to move 0. Operation plate 8 of the detection member 80
When 4 is pressed upward, the main body 81, which has not interfered with the arm 71, protrudes upward from the mounted portion 55 and enters the notch 78, and as shown in FIGS. 10 and 11,
The detection member 80 reaches the detection position. At this time, the main body 8
The upper surface 81a of No. 1 is arranged so as to be recessed below the upper surface 71a of the arm portion 71, and the retaining projection 83 collides with the stopper portion 63 to prevent the detection member 80 from coming out upward from the detection position. There is. In this way, the detection member 8
Since 0 can be moved to the detection position, the lever 70 is rotated to the fitting position, and it is detected that both connectors 10 and 20 are properly fitted. At this time, the operator can easily visually confirm the vertical position of the detection member 80 from behind. At this detection position, the portion of the main body 81 that protrudes above the mounted portion 55 is arranged close to the peripheral surface of the cutout portion 78. Therefore, even when a force that causes the lever 70 to erroneously rotate from the fitting position to the initial position side in the normal fitting state, the holding projection 57 is locked in the fitting position holding hole 77 and the main body Part 81
Since the peripheral surface of the cutout portion 78 abuts on the protruding portion of the lever 70 in the rotation direction of the lever 70, the rotation operation of the lever 70 is doubly restricted. As a result, both connectors 10,
20 can be firmly held in a properly fitted state. In order to remove both connectors 10 and 20, after moving the detection member 80 from the detection position to the standby position, the lever 70 is rotated from the fitting position to the initial position side.
Try to leave 0.

As described above, according to this embodiment,
Until the lever 70 reaches the fitting position, the movement of the detection member 80 is restricted by interfering with the arm portion 71 arranged above the detection member 80. When the lever 70 reaches the fitting position,
Since the detection member 80 is allowed to move without interfering with the arm portion 71 retracted from above, the rotation of the lever 70 depends on whether or not the detection member 80 can be moved from the standby position to the detection position. The position can be easily discriminated, and thus the fitting state of both connectors 10 and 20 can be detected.

Moreover, the detection member 80 is accommodated in the mounting recess 58 formed by retracting the rear wall 52 of the cover 50 inward, and the rear surface 84a of the operation projection plate 84 which is the rearmost surface of the detection member 80 and the mounting surface. Since the rear surface 52a of the rear wall 52 excluding the recess 58 is arranged substantially flush, the detection member 80 is housed in the mounting recess 58 without protruding from the cover 50, and the outer shape can be made clear. .

Further, when the detecting member 80 is moved to the detecting position, the upper surface 81a of the detecting member 80 is arranged so as to be recessed below the upper surface 71a of the arm portion 71 of the lever 70. Can be housed without protruding from the lever 70, and the outer shape in the fitted state can be made clear. In addition, the housing 21
The electric wire led out from the rear surface side is bent in the cover 50 and pulled out to the right side of the cover 50, and the detection member 80 is provided on the rear surface of the cover 50 (the surface where the electric wire is not led out).
Since the electric wire is attached, the electric wire does not interfere with the operation of the detection member 80, and the position of the detection member 80 can be easily confirmed visually.

The detection member, which is mounted and placed at the standby position, is prevented from moving to the detection position by interfering with the lever until the lever reaches the fitting position, and the lever is set to the fitting position. When it reaches, the lever type connector is characterized in that it does not interfere with the lever retracted from the front in the moving direction and is allowed to move to the detection position. 2. The detection member is mounted in a mounting portion that is provided by being retracted inward from an outer surface of the first connector that is substantially orthogonal to a rotation direction of a lever, and the outer surface of the mounted detection member is the outer surface of the mounting member. The lever-type connector according to claim 1, wherein the lever-type connector is arranged at a position flush with the outer surface of the first connector or at a position retracted inward. 3. When the detection member reaches the detection position, the front surface in the moving direction of the detection member is arranged at a position flush with the outer surface of the lever or in a position retracted rearward in the moving direction. The lever-type connector according to claim 1 or 2, which is characterized.
